You are 100% correct that the hissing from a bad tank o-ring would come from the asa. All I'm saying is 1) someone may hear hissing in general and mistake it from somewhere else (as my local shop can attest) and 2) simply check that first before going into the internals. If the o-ring is fine move on to the next item...
